STEAM-TURBINE.

, To' all whom it may concern:

Re it known that I, PAUL c. OS'CANYAN, a

l resident of EastOrange in the county of Es-y sex and State of New Jersey, have invented certain new and useful Improvements' in `Steam- Turbines; and I d'0 hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and usethe same.

My invention relates to steam-turbines, the

i object of the invention being to provide a turbine of that class having radial low'of Huid or horizontal ow with several annular adiabatic expansion-chambers and-one.. or more Series of vanes or buckets between said cham-` a turbine having a minimumnumber'of parts.

`With these objects in view theinvention` .consists in certain-novel features of construe# tion and combinations and arrangements of parts, as will be more fully hereinafter der scribed, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in vertical cross-section, illustrating my improvements. Fig. 2 is a fragmentary face view of the rotary element. Fig. 3 is a fragmentaryiface view of the stationary element. Fig. 4 is a side view of the casing, and Fig. 5 is a view in longitudinal section, illustrating a modification.

1 represents a casing having centralbearings 2 for a shaft 3, on which is secured my improved rotary element 4, mounted in the casing. This rotary element 4 is of circular formation and is provided at intervals at both sides with twin annular series of buckets 5 Y and 6, there being four of these twin series shown, although a greater or-less number may be employed, 4if desired. The inner faces of the casing lsides are provided with twin annular serles of dlrecting-vanes 7 one serles being located 1n advance ofthe serles of buckets 5 and the other series of directing-vanes located-between the buckets 5 and 6. 'The ro-- All of the receivingchambers A10 are, conrt row. Qf. stati.0nnry .vanes ,Parabolic in., @tolse-,Section `Wb,i.. h, ,drecttber -steam -against the first row of buckets 5 upon understood.

element are so shaped asto form in advance of each twin seriesof` buckets and vanes annular chambers or passages 9 andannularred ceivingchambers l0, gradually increasing throughout that series of buckets, when another annular nozzle or passage is formedand receiving-chamber provided for the next series 6o of buckets, each succeeding -nozzle and re-` f ceiving-chamberfrom the axis outward increasing in size, and the steam from the outer series of buckets escapes through outlet 11.

nected by pipes 12 with inlet-chambers 8, and` .cocks 13 are provided in said pipes tofregulate the supply from thev expansion-chambers to the receiving-chamber to properly balance the pressure of steamthroughout the turbine. 7o The operation of my improvements is'as fol-,frk

lows.: Steam is admitted at the inlets 8*?81jfto the'annular chambersl on each sideofthe rotating element at n1preSSnre.of,-Say,,one hundred nnd iiftyfponnds.: It iS thenv adia- 7s batically expanded in the annularchambergr to, sav. one hundred pounds, Vand. the lknfetid energy developed isabsorhedas folglowsgl'llhe steam upon leaving the passagestlkqsithe 7, Which are 8o the rotating element, thereby imparting a ro- Y tary motion thereto. The kinetic energy that is not absorbed is directed against the next 8s row of directing-vanes 7, which directsv the .steam against the next row of buckets 6,

vit exhausts at opening 11 to either the atmosphere or condenser. Y

In the modification shown in Fig. 5 my invention is disclosed upon a'horizontal-low turbine, in which steamenters yat 14 and exhausts at 15, and the kinetic energy is developed and absorbed in the same manner as in the preferred form of my invention, as will be readily A great many slight changes might bel made in the general formand arrangement of the parts described and pointed out without departing from myfinvention, and hence IV do not IOS restrict mysell:` to the precise details set forth, but consider myself at liberty to make such `slight changes and alterations as fairly fall Within the spirit and scope of my invention. Having fully described my invention, what I claim as new, and desire to secure by Letters the buckets to absorb the kinetic energy de- Veloped by said chambers.

3. In a turbine, the Icombination with a rotating element, a stationary element, and said elements so constructed as to form annular chanbers to adiabatically expand the elastic Hui 4. In a radial-oW-turbine, the combination of a stationary element, a rotary element, and

' both elements constructed to form between them annular lchambers to adiabatically expand the elastic fluid.

5. -In a radial-110W turbine, the combination with a casing, and a shaft-therein, of a rotary element in the casing secured on the shaft, several series of buckets on both lsides of the rotary element, several series of directing-vanes on the casing, and said rotary element and casing soconstructed as to form annular chambers at each ser-ies of buckets to adiabatically expand the elastic iiuid.

6. Ina radial-How turbine, the combination with rotating and stationary elements forming a series of annular chambers for the adiabatic expansion of steam, said chambers increasing in area from the axis to the periphery of the rotating element.

7. A radial-flow turbine having a rotary member balanced against pressure and a stationary member, each inner side of said stationary member and each side of the rotating member forming a series of annular chambers constructed to adiabatically expand the elastic fluid.

8. A radial-flow turbine, the combination of a balanced rotary member, vanes or buckets on each side of said rotary member, and a stationary member on each side of said rotary member constructed to form a series of annular chambers for the adiabatic expansion of the elastic fluid.

9. An elastic-fluid turbine having a series of annular chambers constructed to adiabatically expand the elastic fluid, each chamber having a by-pass by which the pressure in said chambers can be adjusted.

10. Aradial-iow turbine having a series of annular chambers constructed to adiabatically expand the elastic Vfluid, and each chamber having a by-pass by which the pressurein said chambers may be adjusted.

11. In a radial-110W turbine, the combination of a rotating and stationary element forming a series of annular chambers constructed `to adiabatically expand the elastic fluid, each chamber having a by-pass by which the pressure therein may be adjusted.

In testimony whereof I have signed this specification in the presence of two subscribing Witnesses.
